Currently, we don't configure validation manually, or at least not completely. We're using Spring and I guess the corresponding configuration is...

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>

A colleague of mine (Sascha Fröhlich) will try to find a solution using a META-INF/validation.xml configuration.

Nevertheless, I guess that a release would resolve the issue in the best possible way (no additional clutter, no workaround, etc).
